[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Specific Implementation Example 1: Please refer to Figures 1 to 7In this embodiment of the present invention, a spray washing device for metal strip includes a hollow spray washing box 7, a spray washing chamber 8 installed inside the spray washing box 7, and a first drying assembly 9. The left and right sides of the spray washing box 7 have a first through hole 701 and a second through hole 702 for feeding and discharging, respectively. The first drying assembly 9 is installed near the second through hole 702. The spray washing chamber 8 includes a first support base 901, a second support plate 802, an upper limit plate 803, and a lower limit plate 804. The first support base 901 and the second support plate 802 are symmetrically and vertically fixed to the bottom surface of the spray washing box 7. The upper limit plate 803 is located between the first support base 901 and the second support plate 802, and the lower limit plate 804 is located below the upper limit plate 803. The metal strip 1 passes vertically between the upper limit plate 803 and the lower limit plate 804 to the first drying assembly 9. Please refer to [link to previous document]. Figure 8 In actual installation and use, a guide mechanism 10 can be set on the outside of the first through hole 701 of the spray washing box 7 to allow the metal strip 1 to be conveyed vertically into the spray washing box 7; the left and right sides of the upper limit plate 803 are bent downward to form a first arc surface 803-1, and the left and right sides of the lower limit plate 804 are bent upward to form a second arc surface 804-1. The lower limit plate 804 is provided with a first drain hole 804-2 which is connected to a water pump through a pipe. The water from the high-pressure water pump flows out through the first drain hole. Water is sprayed upwards from the water hole 804-2 to rinse the metal strip 1 in the spray washing chamber 8. The upper limit plate 803 has a downward curved surface structure on both sides. When the water is sprayed from bottom to top, it will be sprayed onto the upper limit plate 803 and then pressed down onto the metal strip 1 again, rinsing the metal strip 1 once more. Using the first spray washing zone 6, high-pressure clean water is sprayed onto the metal strip 1 to wash away oil particles and residual liquid, preventing them from being carried into subsequent processes.

[0020] The first drying assembly 9 includes a first support base 901, a first air knife 902, and a second air knife 903. A first air duct 904 is installed below the first support base 901 for connecting an air supply device to provide air to the first air knife 902 and the second air knife 903. The first air knife 902 and the second air knife 903 are fixed above the first support base 901 and are both installed perpendicular to the first support base 901. The first air knife 902 and the second air knife 903 have the same structure and are symmetrically arranged front and back on the first support base 901. The first air knife 902 is installed obliquely on the first support base 901. The included angle α between the first air knife 902 and the second air knife 903 is 90-120 degrees. In this embodiment, the included angle α between the first air knife 902 and the second air knife 903 is 60 degrees. The first air knife 902 includes a hollow cavity. The first air knife body 902-1 has a rectangular structure. The end face of the first air knife body 902-1 near the second air knife body 903 has a conical air outlet 902-2. The tip of the air outlet 902-2 is the air outlet 902-3, which is set vertically and has a flat structure. Both the first air knife 902 and the second air knife 903 are inclined to dry the metal strip 1 passing between the first air knife 902 and the second air knife 903. The airflow "cuts obliquely" along the surface of the metal strip 1, generating a transverse shearing force, which is more conducive to blowing the liquid away from the surface of the metal strip 1. At the same time, since the metal strip 1 is transported in a vertical direction, it further prevents the liquid from remaining on both sides of the metal strip 1.

[0021] Compared with the prior art, the metal strip spraying and washing device of this application has a simple layout and easy operation. It can be directly connected to the rear of the cleaning equipment. The metal strip enters the spraying chamber through the first through hole of the spraying box. The vertically placed metal strip is washed with high-pressure water. All the dirt is removed in one go by the washing pull force, resulting in a cleaner cleaning. Moreover, after the lower part of the metal strip is washed in the spraying chamber, the water that is pressed to the upper limit plate can clean the strip again when it flows down, forming repeated washing and enhancing the overall cleaning effect.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the foregoing exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
